Lord Beckett and members of the EIT Co. spot the Black Pearl in the distance making its way towards land. As a
precaution, Lord Beckett orders a cannon to be shot towards Captain Jack Sparrow. The cannonball goes a horizontal
distance of 275 m after leaving the 100. m high cliff. If the cannonball was launched from horizontal, at what velocity
did it leave the cannon? At what velocity (resultant speed + angle) did it hit the sea? (Clearly, they missed the ship!)
Show work
Answer:
Explanation:
The cannonball goes a horizontal distance of 275 m . It travels a vertical distance of 100 m
Time taken to cover vertical distance = t ,
Initial velocity u = 0
distance s = 100 m
acceleration a = 9.8 m /s²
s = ut + 1/2 g t²
100 = .5 x 9.8 x t²
t = 4.51 s
During this time it travels horizontally also uniformly so
horizontal velocity Vx = horizontal displacement / time
= 275 / 4.51 = 60.97 m /s
Vertical velocity Vy
Vy = u + gt
= 0 + 9.8 x 4.51
= 44.2 m /s
Resultant velocity
V = √ ( 44.2² + 60.97² )
= √ ( 1953.64 + 3717.34 )
= 75.3 m /s
Angle with horizontal Ф
TanФ = Vy / Vx
= 44.2 / 60.97
= .725
Ф = 36⁰ .
what is the wavelength of waves at the beach if they have a frequency of 0.3 Hz and they move at 7.1 m/s?
Answer:
23.67 m
Explanation:
We are given;
Frequency; f = 0.3 Hz
Speed; v = 7.1 m/s
Now, formula to get the wavelength is from the wave equation which is;
v = fλ
Where λ is wavelength
Making λ the subject, we have;
λ = v/f
λ = 7.1/0.3
λ = 23.67 m
which of the following quantities can be measured in the same units as Work?
speed times velocity, momentum time speed, forces times velocity, kinetic energy, mass times acceleration, kumquats, potential energy, momentum, weight times acceleration
Answer:
Kinetic energy and potential energy.
Explanation:
Kinetic energy is directly proportional to the mass of the object and to the square of its velocity: K.E. = 1/2 m v^2. If the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared. Kinetic energy is usually measured in units of Joules (J); one Joule is equal to 1 kg m^2 / s^2.
The formula for potential energy depends on the force acting on the two objects. For the gravitational force, the formula is P.E. = mgh, where m is the mass in kilograms, g is the acceleration due to gravity (9.8 m/s^2 at the surface of the earth) and h is the height in meters. Notice that gravitational potential energy has the same units as kinetic energy, kg m^2/s^2. In fact, all energy has the same units, kg m^2/s^2, and is measured using the unit Joule (J).
Work is also measured with the unit Joule (J).

Could I get help on this question please . My parents won’t help me /:
Answer:
Tarzan will be moving at 7.4 m/s.
Explanation:
From the question given above, the following data were obtained:
Height (h) of cliff = 2.8 m
Initial velocity (u) = 0 m/s
Final velocity (v) =?
NOTE: Acceleration due to gravity (g) = 9.8 m/s²
Finally, we shall determine how fast (i.e final velocity) Tarzan will be moving at the bottom. This can be obtained as follow:
v² = u² + 2gh
v² = 0² + (2 × 9.8 × 2.8)
v² = 0 + 54.88
v² = 54.88
Take the square root of both side
v = √54.88
v = 7.4 m/s
Therefore, Tarzan will be moving at 7.4 m/s at the bottom.

Approximately where is it currently high tide on Earth? Group of answer choices wherever it is currently noon anywhere that ocean water laps upon the shore on the portion of Earth facing directly toward the Moon and on the portion of Earth facing directly away from the Moon only on the portion of the Earth facing directly toward the Moon
Answer:
Option D, only on the portion of the Earth facing directly toward the Moon
Explanation:
Tides are caused by the gravitational pull of moon. The part of earth that faces the moon experiences the highest gravitational force and hence the high tides will occur in this regions only. The regions that do not faces the moon experiences low tides. It is the gravity of moon that attracts the ocean water towards itself.
Hence, Option D is correct

It is winter. You are very cold. Your body systems cooperate and respond to the cold in three ways in an effort to keep you warm. Choose the answer that is NOT correct.
Your nervous system slows down and the impulses that move your muscles also slows, helping to retain heat.
The body will try to generate heat itself by allowing muscles and organs to shake within the body: this is known as shivering.
Blood flow is diverted from muscle tissue to fat. The rapid decomposition fat (adipose) tissue generates heat energy that helps to raise the body's temperature.
Cold causes blood vessels to constrict and blood flow resistance to increase. Reducing blood flow to the skin and the extremities reduces heat transferred to the environment.
Answer:
The third option
Explanation:
A and B are true because this can be noticed by just any human. So then you are left with C and D. With these two, D makes more sense. Since when someone gets cold, their blood flow is reduced starting in areas like your fingers, hands, toes and feet. These areas get the coldest since they are the smallest and furthest away from the rest of your body. Also since these areas touch surfaces more than other areas, they will have less heat to transfer.

Answer:
In a system with a hanging mass and an inextensible wire, the force is proportional to the sino, in the case of small oscillations, approximately the stop angle, this hiss is lost, the calibration for large amplitudes is lost.
Explanation:
In a spring-mass system the restoring force created by the spring is proportional to displacement from the equilibrium position, therefore this watch does not require streamlining as the amplitude of movement increases.

Examples of Newton's third law of motion are ubiquitous in everyday life. For example, when you jump, your legs apply a force to the ground, and the ground applies and equal and opposite reaction force that propels you into the air. Engineers apply Newton's third law when designing rockets and other projectile devices.
Explanation:
What provides most of the force to allow the runners to move?
Answer:
When you are running the most important force that you should understand is friction. Friction is a force that opposes movement between two objects, but for runners friction makes you faster. Friction gives you a better and more efficient way to use your energy into speed.
The reaction force provided by the tracks as the runners press their feet against the track provides the maximum force.
What is newtons third law of motion?The newton's third law of motion states that every action has a equal and opposite reaction
Given is to find what force allow the runners to move.
The reaction force provided by the tracks just before the runners start running as they press their feet against the track provides the maximum force.
